ASTM A694 o se fa'ailoga uamea Amerika
ASTM A694 Forgings mo Flanges Paipa Pa'u Uamea ma Alloy Steel, Fa'apipi'i, Valves ma Vaega mo Meafaigaluega Fa'asalalauina Maualuga.
A694 e iai le aofa'i F42 U46 U48 U50 U52 U56 U60 U65F70
A694 o se sila uamea i le Iunaite Setete, ma o lona vailaʻau vailaʻau e latalata i le Q345D i Saina.Q345D e manaʻomia ona faʻataʻitaʻiina togafitiga faʻamaʻi vevela aʻo leʻi oʻo atu i mea faʻainisinia o le A694 F60.

E le gata i lea, o le ASTM A694 Gr.F60 foi o se mea uʻamea uʻamea maualalo e faʻaaogaina mo paipa paipa i lalo o le maualuga o le mamafa ma le vevela maualuga, o lea e taʻua ai foi A694 F60 faʻapipiʻi maualuga.
O lenei mea e masani ona faʻaaogaina mo fesoʻotaʻiga paipa maualuga i totonu o le suauʻu, kesi faʻalenatura ma fale kemisi, ma e maualuga le malosi ma le faʻafefe.

A o le tulaga maaa oASTM A694 Gr.F60,e leai se mana'oga ma'a'a fa'apitoa.O le maaa e faʻalagolago i tulaga faʻapitoa o le vevela ma le tulaga o mea.E masani lava, o le tulaga maaa o mea A694 F60 e tofotofoina i lalo ole Brinell maaa (HB) poʻo le Rockwell hardness (HRC).O le tau maaa o le a eseese e tusa ai ma le vailaʻau vailaʻau, tulaga vevela vevela ma le gaosiga o meafaitino.

Ave le fa'au'u uelo o le A694 F60 e fai ma fa'ata'ita'iga e fa'amatala ai:

A694 F60fa'au'u uelo fa'amaue le faigofie ona deform, e lelei faʻamaufaʻailoga ma faʻaaogaina lautele.E faʻatatau i paipa faʻatasi ma le tele o le mamafa poʻo le fesuiaiga o le vevela poʻo le maualuga o le vevela, maualuga maualuga ma le maualalo o le vevela.E masani ona faʻaaogaina mo le fesoʻotaʻiga o paipa ma valve ma PN sili atu nai lo le 2.5MPa;E fa'aaogaina fo'i i paipa e fa'asalalauina ai fa'asalalauga taugata, mu ma pa.E umi lona soifua tautua.E tusa ai ma faʻamaumauga o suʻega faʻamaʻi, o lona ola tautua e mafai ona oʻo atu i le 100 tausaga ma e tau le manaʻomia le tausiga.O le mea lea, o lona tau fa'atinoga-tau e matua'i lelei, o lona tau fa'agaioiga e maualalo, ma o ana fa'amanuiaga tau tamaoaiga e taua tele.

A694 F60 butt welding flange o loʻo faʻaalia e ala i fesoʻotaʻiga faʻalagolago ma saogalemu, faigofie ma vave le fausiaina, lelei le tumama ma le puipuiga o le siosiomaga, faʻaitiitia o le mamafa o le tafe, malosi le fesoʻotaʻiga, faʻapipiʻi matala ma natia, leai se faʻafouina ma le tausiga, faʻaleleia le tamaoaiga, ma lautele fa'aoga avanoa.E faʻatatau i le vaʻaia maualalo o le suavai e pei o le malulu ma le vai vevela, vai inu saʻo, faʻavevela, malulu, puipuiga o le afi, kesi, ma isi, faʻapea foʻi ma vailaʻau, meainu, meaʻai Low-pressure fluid transmission in chemical industry ma isi alamanuia.
